> 1. Does the JLCooper CS-10 remote controller work with Cubase Essential 5
?
Not sure if it will work straight out of the box (not familiar with the
controller) but if it sends midi it can be made to work.
A Midi-to-USB-cable is the first step. You could then install midi-yoke and
midi-ox and have midi-ox translate whatever codes the controller sends out
to whatever codes Cubase needs to see.
This will require a lot of figuring-out, however.
A cheap alternative may be a Behringer BCF2000 set to mackie control
emulation, that should work with cubase, USB built-in already
